Arizona sells its 2026 marketplace health plans through the federal exchange at HealthCare.gov, and this year the numbers changed in a big way. Premiums rose across every insurer, and the enhanced premium tax credits that kept coverage cheap from 2021 through 2025 expired on December 31, 2025. For 2026, a single Arizonan earning up to about $62,600 and a family of four earning up to about $128,600 can still qualify for a premium subsidy, but anyone above 400% of the federal poverty level now pays full price with no help. This guide breaks down what plans actually cost, who qualifies for savings, and how much you can expect to pay.
What Changed for Arizona in 2026
Two things drove up costs for Arizona marketplace enrollees this year.
First, insurers raised rates. Arizona carriers filed 2026 increases that averaged roughly 29% for Silver plans and 33% for Bronze plans, with some individual plan changes ranging much higher. Carriers pointed to rising medical and prescription costs and uncertainty around federal subsidy policy.
Second, and more consequential for your monthly bill, the enhanced premium tax credits ended. From 2021 through 2025, a temporary federal law lowered what everyone paid and removed the old income cap on subsidies. That law was not extended. For 2026 coverage, the rules revert to the original Affordable Care Act structure: subsidies phase out completely above 400% of the federal poverty level, and the share of your premium you are expected to pay at every income level went up.
Even with these changes, most Arizonans buying on the marketplace still get help. About 90% of Arizona marketplace enrollees receive some level of financial assistance based on income.
Arizona 2026 Marketplace Premium Costs
Arizona's individual marketplace is now made up entirely of HMO plans in 2026. Blue Cross Blue Shield of Arizona discontinued its marketplace PPO plans, so enrollees who had a PPO needed to switch to an HMO during open enrollment. Insurers offering 2026 plans in Arizona include Blue Cross Blue Shield of Arizona, UnitedHealthcare, Oscar, Cigna, Ambetter, Imperial Insurance Companies, and Antidote Health, though the exact mix of carriers varies by county.
Here are approximate full-price (before subsidy) monthly premiums for a middle-aged adult by metal tier in Arizona for 2026:
| Metal Tier | Approx. Monthly Premium | Best For |
|---|
| Bronze | around $603 | Lowest premium, highest out-of-pocket costs |
| Silver | around $660 | Standard coverage, unlocks cost-sharing reductions |
| Gold | around $787 | Higher premium, lower deductibles and copays |
| Platinum | Not offered in Arizona | N/A |
These are averages. Your actual premium depends on your age, your county, whether you use tobacco, and the specific plan you pick. Younger enrollees pay less and older enrollees pay more. Most people never pay these full-price amounts because a premium tax credit reduces the monthly bill.
Who Qualifies for a Subsidy in 2026
Arizona uses the federal poverty level (FPL) to determine subsidy eligibility. For 2026 coverage, eligibility is based on the 2025 poverty guidelines. To get a premium tax credit, your projected 2026 household income generally needs to fall between 100% and 400% of the FPL.
Below 100% of the FPL, most adults in Arizona qualify for AHCCCS, the state's Medicaid program, instead of a marketplace subsidy. Arizona expanded Medicaid, so adults with income up to 138% of the FPL (about $22,025 for one person in 2026) are typically covered by AHCCCS rather than the marketplace.
Here is the 2026 marketplace subsidy income range by household size:
| Household Size | 100% FPL (approx. Medicaid floor) | 400% FPL (subsidy cutoff) |
|---|
| 1 | $15,650 | $62,600 |
| 2 | $21,150 | $84,600 |
| 3 | $26,650 | $106,600 |
| 4 | $32,150 | $128,600 |
| 5 | $37,650 | $150,600 |
| 6 | $43,150 | $172,600 |
If your income lands above the 400% column for your household size, you can still buy a marketplace plan, but you will pay the full premium with no tax credit. This is the "subsidy cliff" that returned in 2026. Under the enhanced credits, people above 400% of the FPL had their benchmark Silver premium capped at 8.5% of income. That cap is gone for 2026.
How Much Will You Actually Pay
The premium tax credit works on a sliding scale. The lower your income within the eligible range, the larger your credit and the smaller your monthly payment. The credit is tied to the second-lowest-cost Silver plan in your area, called the benchmark plan, but you can apply it to any metal tier.
A few examples of how this plays out in Arizona for 2026:
- A single adult earning around $30,000 (roughly 190% of the FPL) will still receive a substantial tax credit and typically pays a modest monthly amount toward a benchmark Silver plan.
- A family of four earning $50,000 (well within the eligible range) may qualify for several hundred dollars per month in premium tax credits.
- A single adult earning $65,000 (above 400% of the FPL) receives no credit in 2026 and pays the full premium, which for a Silver plan runs around $660 per month.
Because the exact amount depends on your age, county, and the benchmark plan where you live, the only way to see your real number is to enter your details on HealthCare.gov or run a subsidy calculator. Subsidy-eligible Arizona enrollees have historically paid an average close to $133 per month after tax credits, though that figure is expected to rise in 2026 as credits shrink.
Cost-Sharing Reductions: Extra Savings on Silver Plans
If your income is at or below 250% of the FPL, you qualify for cost-sharing reductions (CSR) on top of the premium tax credit, but only if you choose a Silver plan. CSR lowers your deductible, copays, and out-of-pocket maximum, sometimes dramatically. For lower-income enrollees, a Silver CSR plan can end up with better benefits than a Gold plan at a lower cost.
Here is the 250% FPL ceiling for CSR eligibility in 2026:
| Household Size | 250% FPL (CSR ceiling) |
|---|
| 1 | $39,125 |
| 2 | $52,875 |
| 3 | $66,625 |
| 4 | $80,375 |
If you fall in this range, picking Silver instead of Bronze is usually the smarter move because you keep both the premium credit and the CSR benefit. Choosing Bronze forfeits the cost-sharing reduction entirely.
How to Enroll in an Arizona Marketplace Plan
Arizona does not run its own exchange, so you enroll through the federal marketplace. Open enrollment for 2026 coverage ran from November 1, 2025 through January 15, 2026. If you missed it, you can still enroll if you have a qualifying life event such as losing job-based coverage, moving, getting married, or having a baby, which opens a special enrollment period.
Follow these steps:
- Go to HealthCare.gov and create an account or log in to your existing one.
- Start an application for 2026 coverage and enter your Arizona ZIP code, household size, and projected annual income.
- Review your subsidy eligibility. The site calculates your premium tax credit and tells you whether you qualify for cost-sharing reductions.
- Compare plans by metal tier. Look at the full premium, the premium after your credit, the deductible, and the out-of-pocket maximum, not just the monthly price.
- Check the provider network. Because Arizona is HMO-only in 2026, confirm your doctors and preferred hospitals are in-network before you pick a plan.
- Enroll and pay your first premium. Coverage is not active until the first payment clears.
If you want live help, HealthCare.gov lists local assisters and licensed brokers who can walk you through it at no cost. The Arizona Department of Insurance and Financial Institutions (DIFI) also publishes open enrollment resources.
Marketplace vs. AHCCCS: Which Applies to You
If your household income is low, you may not need a marketplace plan at all. AHCCCS, Arizona's Medicaid program, covers adults up to 138% of the FPL and children up to higher thresholds through KidsCare. Medicaid has no monthly premium for most enrollees, which makes it far cheaper than even a subsidized marketplace plan.
| Program | Income Range (Individual, 2026) | Monthly Cost |
|---|
| AHCCCS (Medicaid) | Up to about $22,025 (138% FPL) | Usually $0 |
| Marketplace with subsidy | About $22,025 to $62,600 | Reduced by tax credit |
| Marketplace, no subsidy | Above $62,600 (400% FPL) | Full premium |
When you apply on HealthCare.gov, the system automatically checks whether your income makes you eligible for AHCCCS and routes you accordingly. You do not have to guess which program fits.
Frequently Asked Questions
How much do Arizona marketplace health plans cost in 2026?
Full-price monthly premiums in Arizona for 2026 average around $603 for Bronze, $660 for Silver, and $787 for Gold plans for a middle-aged adult. Most enrollees pay far less after applying a premium tax credit. Your final cost depends on your age, county, income, and the plan you choose.
What is the income limit for Arizona ACA subsidies in 2026?
For 2026, premium tax credits are available to households with income between 100% and 400% of the federal poverty level. That is roughly $15,650 to $62,600 for one person and $32,150 to $128,600 for a family of four. Above 400% of the FPL, no subsidy is available.
Why did my Arizona health insurance get more expensive for 2026?
Two things happened. Insurers raised rates by an average of roughly 29% for Silver plans, and the enhanced federal premium tax credits that were in place from 2021 through 2025 expired at the end of 2025. The combination means higher premiums and smaller subsidies for most enrollees.
Can I still get help if I earn more than 400% of the poverty level?
Not in 2026. The enhanced credits that had removed the income cap expired, so the 400% FPL cutoff is back. If your income is above that threshold, you can still buy a marketplace plan but you pay the full premium with no tax credit.
Do Arizona marketplace plans still have PPO options in 2026?
No. Blue Cross Blue Shield of Arizona discontinued its marketplace PPO plans for 2026, and the Arizona individual marketplace is now made up entirely of HMO plans. Check that your providers are in-network before enrolling, since HMOs generally do not cover out-of-network care.
What if my income is too low for a marketplace subsidy?
If your income is below 100% of the FPL, you likely qualify for AHCCCS, Arizona's Medicaid program, which covers adults up to 138% of the FPL at no monthly premium for most people. When you apply through HealthCare.gov, it automatically checks your AHCCCS eligibility.
When can I enroll in a 2026 Arizona marketplace plan?
Open enrollment for 2026 ran from November 1, 2025 through January 15, 2026. Outside that window, you can only enroll if you have a qualifying life event such as losing other coverage, moving, marriage, or a new baby, which triggers a special enrollment period.
